Re: Flow direction - baseboard heating
Can you post some photos of the boiler and associated piping? The diagram doesn't make much sense.
You said the system is 12 years old. Did it ever work right?

Re: Steam pressure question
I don't recall whether this is a one pipe or a two pipe system. If it is a one pipe system, the @mattmich is correct, since in a one pipe system there are no returns at atmospheric pressure. All that will happen is that valves and vents will be overpressured, and leak or spit or hiss or otherwise misbehave.
If this were a two pipe system, in which the returns are at atmospheric pressure, then yes you would get water stacked up into the dry returns — and things would be very unhappy.
Re: Boiler radiator valves siezed
why a combo boiler. Your not going to get a return on investment.

Re: Jensen indoor Wood Boiler w/Hydronic Oil - Oil runs all the time?
It's really the piping that dictates how the control has to function. With a tankless coil in the boiler, it needs to stay hot.

Re: Vitodens 100- normal operating sound?
I'm not as expert as some but I have installed a half dozen 100s and serviced a few. That is not a normal sound. That's not even normal with the cover off. Sounds like something restricting the air intake? deserves investigation.

Re: Boiler radiator valves siezed
Those are good old fashioned plain vanilla radiator valves. They can be disassembled quite easily and brought back into splendid operating condition. As has been suggested, though, a little penetrating oil on the packing nut will make life a lot easier…
No need to replace them. With a little care and maintenance they will still be working just fine long after a shiny new valve has gone to the dump.
Re: Jensen indoor Wood Boiler w/Hydronic Oil - Oil runs all the time?
Fair enough, @EdTheHeaterMan — but then the aquastat must be wired to turn off the oile burner when it's happy. Which it isn't. And — perhaps I'm missing something — wouldn't shutting off power to the burner using the aquastat eliminate any post purge?
Re: One year old Williamson-Thermoflo heat exchanger failure
Good that they finally stepped up.
We see on this forum that the quality of some installs is terrible (not you @SuperTech )
so I can understand the MFGs providing some pushback but You @SuperTech have the testing and documentation to back up your claim.
Good job
Re: Balancing
Any ideas what could have caused this dramatic change?
How about a serious lack of maintenance with nobody to care for the mechanicals on a yearly basis and the expectation by the congregation that it will run by itself forever!!

Re: Armstrong Air Furnace GUK075D14-3A
There is a set of instructions on a plate or sticker of every gas furnace since 1950s on how to light a gas furnace. Even the ones with electronic ignition (no pilot)
